GAS-FIXTU RE.

SPECIFICATION forming part of Letters Patent No. 574,907, dated January12,1897.

Application filed June 24, 1896. Serial No. 596,684:- (No model.)

To all whom it may concern.-

Be it known that I, EDWARD A. O. KAYSEL, -a citizen of the UnitedStates, residing at New York city, in the county and State of New York,have invented a certain new and useful Improvement in GasFixtures,' ofwhich the following is a specification.

My invention relates to an improvement in combination gas and electricfixtures and such fixtures where it is desirable to have, besides thegasway, another passage-way through the same pipe in which to placewires for electric lamps, gas-lighting devices, &c.

By my invention I have made it possible to I 5 carry the wires in thesame pipe with the gas, safely maintaining the necessary insulation ofthe wires, while controlling the gas in the way usual in simplegas-fixtures.

Referring to the drawings, where similar letters indicate similar parts,Figure 1 is a view of an arm, either of a chandelier or a bracket,provided with both gas and electrical connections, parts being shown invsect-ion. Fig. 2 shows a modification of such arm with sections of thegas-jet and connection with the main pipe and a view of the form ofgascock claimed herein.

The arm A is made of combination-pipe, well-known to the gas-fixturetrade, having two passages to and b, the lower one of which, b, servesas the gasway from'the main pipe to the jet 13. The cock 0, whichcontrols said gasway, is placed on the arm between the main pipe and thejet instead of being placed upon the jet controlling the way a, asheretofore. This arrangement, besides making a more ornamental fixture,puts the gas-controlling device in a very much more convenient position,allowing the thumb-piece of the cock to extend downward instead of offto the side, as has been the necessary construction heretofore. The cock0 is arranged to control the gasway only and to leave the passage a openand uninterrupted. In order to do this and to place the cock inconvenient position, as well as to insure there being no leakage of gas,it is necessary to have the pipe A arranged so that the gasway Z) shallenter the main body of the cock 0 below the wire-con- 50 duit a. The twoportions of the arm A screw into the main body 0 of the cock. This main.body is cast or bored so that it shall have a large open way 0.extending through it to form a continuation of the pipe-conduit athrough the body of the cock. The lower portion of O is solid, exceptfor a small aperture 1), communicating with the gasway b, and which iscontrolled by the plug D of the cock in well-known manner. This plugextends up through the solid portion of 0' and is held in place by ascrew (1, whose shoulders abut on such solid portion. This screw, itwill be seen, is in the interior of the cock, with a free open spaceabove it forthe passage of the wires. Heretofore the plug D has extendedentirely through the pipe, being secured by a screw in position of the dummy-screw 6 shown in the drawings, and here used merely to gain accessto the screw (1. In order to make connection between the gasway b andthe jet-pipe c, it is necessary to make an aperture f in the lower partof the pipe A, such aperture being covered by the body of the jet B, agroove g in such body encircling thepipe A, connecting said aperture fwith the jet-pipe c. The gasway I) is sealed by solder or in othersuitable manner at a point beyond the jet.

I11 the modification shown in Fig. 2 there is no necessity for thegroove 9 in the main body of the jet-pipe, since the turn given to thepipe A serves to bring the gasway below the pipe-conduit at the pointwhere the cock is placed, and above such pipe-conduit at the point wherethe jet is placed, where nothing more is necessary than the usualaperture through the pipe A from the gasway into the jet-pipe. Themovement of the plug may be limited in its open and closed positions bya pin 7L, carried on the body of the cock and working in a recess 2',cut in a flange on the plug, as shown in Fig. 2, or in any otherappropriate way.

The arm A is connected to the main pipe E, or to the distributing-bodyin the case of a chandelier, through a suitable connection F, having away 12 therein to conduct the gas from said main pipe to the gasway band a way a to connect the pipe-conduit a with the interior of theornamental casing of the bracket or chandelier, from whence the wiresare led away to form proper electrical connections, being concealed fromview by the TOO ordinary methods, The ornamental casing G fits onto ashoulder of F in such position that the wires issuing from Z1 cannotpossibly be cut by the sharp edges of the casin The insulated wiresentering such arm are passed through 1) into the conduit Z), where theylie safe from fear of abrasion. At the point where the gas-cock isplaced the wires pass straight through the large opening provided forthem, made in the main body of said cock, lying over the screw d. W henthe parts of the arm are put together, solder is run along the threadingof the screws, as is usual, to close all joints and make the armgas-tight.

\Vhat I claim is 1. In a fixture, the combination with a gas andelectrical connection, of a pipe-arm having two adjacent parallel waystherein, one a gasway and the other a conduit for wires, said conduitbeing above the gasway at the main pipe connection, a gas-cock havingtwo ways therein corresponding and registering with the ways of saidpipe-arm, and a plug in said gas-cock extending into the gasway only,substantially as set forth.

2. In a fixture, the combination with a gas and electrical connection,of a pipe-arm having two adjacent parallel ways therein, one

a gasway and the other a conduit for wires, said conduit being above thegasway at the main pipe connection, a gas-cock having two ways thereincorresponding and registering with the ways of said pipe-arm, a plug insaid gas-cock extendinginto the gasway only, and entirely clear of theconduit and a dummyscrew in the conduit above said plug, substantiallyas set forth.

In a fixture, the combination with a gas and electrical connection, of apipe-arm having two adjacent parallel ways therein, one a gasway and theother a conduit for wires, said conduit being above the gasway at themain pipe connection, a gascock having two ways therein correspondingand registering with the ways of said pipe-arm, a plug in said gas-cockextending into the gasway only, and a jet-body having a groove andjet-pipe, said groove communicating with the gasway, substantially asset forth.

This specification signed and witnessed this 23d day of June, 1896.
